Application filed. July 7, 1 915. Serial No. 3&433.

To all whom it may concern:

Be it known that 1, CHARLES 'KAUFMANN, a citizen of the United States, and a resident of Santa Ana, in the county of Orange and State of California, have invented certain new and useful Improvements in Lamps and Lamp-Supports, of which the following is a specification.

My present invention relates generally to lamps, and more particularly to lamps and the supports thereof especially adapted for use in connection with automobiles, motorcycles, canoes, launches,'and the like, my object being to provide a simple, strong, and

durable arrangement wherein the lamp proper may be removed from its support and utilized as a spot light in case of trouble.

A further objectof my invention is to provide a lamp of this character whereinthe internal parts are effectively protected against the ingress of dirt, dust and other extraneous matter.

A further object of my invention is to provide a lamp of this character wherein the light bulb may be readily and quickly adjusted to the proper focus and maintained at this point.

Other objects of my invention residing more particularly in the details of construction of the various parts included therein,

will be better understood from the following description of these details, reference being bad therein to the accompanying drawings, forming a part of this specification, and in Which- Figure 1 is a perspective view illustrating the practical application of my improved lamp to the windshield of a motor vehicle, the lamp proper being turned to one side to better illustrate its practically universal support. Fig. 2 is a perspective view illustrating the practical application of the invention and showing the lamp proper removed and utilized as a spot light in case of trouble. Fig. 3 is a detail vertical section taken therethrough substantially on line 3-3 of Fig. 1.

Fig. 4 is an elevation in the same position' as Fig. 1, with certain of the parts broken away and in section to better illustrate their detail connection. Fig. 5 is an enlarged detail section illustrating the dustproof connection between the reflector housing, reflector, and lens. Fig. 6 is a detail horizontal section taken substantially .on line 6-6 of t Fig. 4:. Fig. 7 is a detail perspective view of the reflector removed. Fig. 8 is a similar view of the handle with its cap removed, and Fig. 9 is another detail section illustrating the light bulb and its socket.-

Referring now to these figures, and more particularly to Fig. 4, it will be seen that I provide a handle A having an intermediate depending post A, the handle A normally extending in horizontal position in use, and being tubular in form with a concave rear end A having threads for the reception of a cap B having a concaved inner face abutting the concaved end A of the handle and provided with threads internally thereof to engage the threads of the handle end just mentioned, so as to bring the concaved faces into opposition, thus providing a cavity for the reception of a packing C, the function of which is to closely surround the light cord D extraneous matter within the handle A. The opposite end of the handle A is externally threaded as best seen at A in Fig. 8, for the reception of the internally .threaded Patented Dec. M, iota;

.and prevent the entrance of dirt,dust, and

rear tubular extension E of the reflector housing E, the enlarged outer end of which is provided with a threaded portion E adjacent its annular shoulder E both as best seen by reference to Fig. 5. The shoulder E receives a packing strip F against which is seated the outer flange end G of there flector G, and the threaded portion E is engaged by the internally threaded, ring H having a flange H'by means of whichthe lens ll is firmly held in position with its edge against the flange G of the reflector, a packing F being interposed between the flange H and the lens I whereby, with the packing F and the screw connection between the parts, a thoroughly dust and dirt proof joint is formed, excluding all extraneous matter from the interior of the lens;

The reflector G has a rear tubular extension Gr best seen in Fig. 7, which, as shown clearly in Fig. 4, extends within the forward end of the handle A and is provided withan aperture 9 through which a clamping screw J threaded through the handle A intermediate its ends, mav project into engagement with the socket K of the light bulb whereby to thus secure the socket K and the light bulb K carried thereby, in adjusted position and at the proper focusing point within the reflector. The light cord D extends tions of this bearing L being connected by fromthe rear of the socket'K and through the rear stuffing box of the body A as before described.

The post A depending from the handle A is provided at its lower end w1th a smooth cylindrical portion A below an intermed ate annular shoulder A this smooth cylindrical portion A being adapted to extend withln a split upright bearing L of a swlveled supporting block or member L, the spht pora clamping screw M by means of which the lamp may be secured in adjusted position around the vertical longitudinal axis of the post A. Upon loosening of the clamping screw M, however, the lamp maybe either further adjusted around the axis ust mentioned, or wholly removed from the supporting member L for use as a spot light 1n case of-trouble, as plainly seen by reference to Fig, 2, and in this event conslderable length of light cord D is necessary. When so used it will be seen that the handle A with its integral depending post A, may be firmly grasped in the hand as the llght is manipulated from one part to another of the vehicle or boat in connection with which my improved lamp is mounted, without danger of dropping and breaking the same.

The swiveled supporting member L has a split horizontal bearing L", at one side of its vertical bearing L before mentioned, this split horizontal bearing L being joined by a clamping bolt N.and engaging the outer cylindrical extension 0 of a bracket 0 having inner bent and vertically spaced extensions O opposing the similarly bent and vertically spaced extensions P of a U- shaped'clamping frame P provided with projections P engaging the bracket 0 andfurther connected to the bracket by clamping bolts and nuts Q extending through the clamping frame P and the bracket 0 at points between the projections l? and the bent clamping extremities P, all as'best seen by reference to Figs. 1 and 6. Thus by manipulation of the clamping bolt N, the swiveled supporting member L may be shifted vertically around the axis of the extension 0 of the bracket 0, so that the lamp may be adjusted to either inclined or vertical position. In adjusting the lamp upon the vertical axis of the post A, however, it is to be noted that the outer portion 0 of the bracket is substantially above the plane of its inner clamping end for engagement with various portions of a vehicle or boat, as for instance, the frame of an automobile windshield as indicated at R in Figs. 1, 2, and 4, thus permitting the lamp to be swung completely around, throughout'a full circle. It will furthermore be seen that the several parts of my improved lamp are capable of ready and quick adjustment, are susceptible of practical and effective use for the purposes mentioned, and are at the same time simple, inexpensive, and durable in use.

I claimbi 1. A lamp of the character described including a tubular handle having a post depending therefrom, and having a stuffing box at one end through which a light cord is adapted to extend, a reflector housing having a threaded connection at its inner end with the opposite end of said handle and having a threaded outer portion, a swiveled supporting member in which the lower end of said post is adjustably and reinovably held, a reflector mounted within said housing and having a tubular inner extension projecting within the handle and provided with an aperture, a lens, a clamping ring for the lens having threads engaging the outer threaded portion of the reflector housing, a bulb socket extending through the tubular inner extension of the reflector and to which the light cord is connected, a clamping screw threaded through the handle and extending through the aperture of the reflector extension whereby to engage and adjustably hold the said bulb socket, and a bracket upon which the said supporting member is carried.
